Replacing Fuel Tank Assembly In Craftsman Backpack Blower

If you're looking to replace the fuel tank assembly on your Craftsman gas backpack blower, you've come to the right place. This repair guide will walk you through the process step by step. Before you begin, ensure you have the necessary parts and tools, including a manufacturer-approved fuel tank assembly for your specific Craftsman model. It's also recommended to work in a well-ventilated area and wear appropriate safety gear. Now, let's get started!

How to remove the fuel tank

Step 1: Safety First

Before you begin, make sure you are in a well-ventilated area to avoid inhaling any fumes.

Step 2: Drain the Fuel Tank

Remove the fuel cap and empty the remaining fuel from the tank into an approved storage container. This is important to prevent any spills or accidents during the removal process.

Step 3: Disconnect the Spark Plug Wire

Locate the spark plug wire and disconnect it from the spark plug. This step ensures that the blower cannot start accidentally during the removal process.

Step 4: Remove the Blower Tube

Loosen the thumb screw on the front of the housing and pull off the blower tube. This will give you better access to the fuel tank and its surrounding components.

Step 5: Remove the Air Filter Cover

Remove the screws securing the air filter cover in place and then take off the cover itself. This will expose the carburetor and other parts connected to the fuel tank.

Step 6: Disconnect Fuel Lines

Before removing the fuel tank, you need to disconnect the fuel lines that are attached to it. Use needle-nose pliers to carefully remove the fuel filter from inside the tank, and then pull out the small and large fuel lines through the mounting hole.

Step 7: Remove the Fuel Tank

Now, you can finally remove the fuel tank itself. Start by removing the screws from the front of the muffler guard cover and taking off the guard cover. Then, remove the blower tube thumb screw from the front of the housing. Finally, remove the screws from the right side of the housing and gently pull out the left side of the housing, which should come off along with the fuel tank.

By following these steps, you will be able to safely and effectively remove the fuel tank from your Craftsman gas backpack blower, making it ready for a replacement.

How to remove the fuel lines from the tank

To remove the fuel lines from the tank of your Craftsman gas backpack blower, you will need needle-nose pliers.

First, disconnect the spark plug wire from the plug. Then, use the pliers to fish out the fuel filter from inside the tank. Remove the fuel filter from the end of the small fuel line. Now, pull the small fuel line out of the tank through the mounting hole. Finally, push the large fuel line into the tank through the mounting hole and pull it out of the mouth of the tank.

It is important to keep track of the configuration of the fuel lines so that you can reconnect them correctly later.

How to cut and install the large fuel line

To cut and install the large fuel line of a Craftsman gas backpack blower, follow these steps:

Firstly, cut the large fuel line at an angle. Push the angled end into the tank through the mounting hole, ensuring it goes far enough that you can grab the end through the mouth opening with needle-nose pliers.

Next, cut the angled end of the fuel line to make it straight and install a grommet on the end. Pull the opposite end of the large fuel line until the grommet is touching the side of the tank.

Finally, cut the large fuel line to match the length of the original fuel line. Lubricate the fuel line with a drop of oil to ease threading.

To replace the fuel line, follow these steps:

• Remove the old line from the tank.
• Cut the new, larger line on a 45-degree angle, or trim as necessary, so you can grip it from inside the tank.
• Pull the new line into the tank.
• Cut the other end of the line straight and install the fuel filter.
• Ensure the small vent line comes inside the tank but does not reach the bottom.

How to cut and install the small fuel line

To cut and install the small fuel line for a Craftsman gas backpack blower, follow these steps:

First, before you start, take a picture of where the old lines are connected to the carburettor and the primer bulb for future reference. Then, pull the spark plug wire from the plug. Remove the old line from the tank and remove the fuel filter from the line.

Now, take the new small fuel line and cut one end at a 45-degree angle. You may need to trim it further so that you can grip it from inside the tank. Push the angled end into the tank through the mounting hole. Pull the small line out through the mouth of the tank. Cut the angled end of the fuel line square and attach the fuel filter. Ensure you leave enough line for the fuel filter to reach the bottom of the tank.

Push the small line back into the tank through the mouth opening. Tug the other end of the small line until the filter rests on the bottom of the tank. Cut the small fuel line to the same length as the original small fuel line.

Finally, reinstall the left side of the housing. Position the housing near the leaf blower and thread the fuel lines through the hole in the housing near the carburettor. Position the handle properly and push the housing back together, making sure the eyelet for the starter pull cord is correctly positioned. Insert the thumb screw in the housing at the front of the blower and rotate the screw until it catches the nut; don't tighten it yet. Loosely install two other housing screws to keep the housing in place while you install the fan cover.

How to reinstall the fuel tank

To reinstall the fuel tank of your Craftsman gas backpack blower, follow these steps:

Firstly, ensure that you have already drained the fuel tank into an approved storage container in a well-ventilated area. Now, reconnect the fuel lines to the carburetor, ensuring they are correctly configured as per the manufacturer's instructions.

Next, insert the carburetor into the air box, positioning the throttle and choke levers correctly. Reinstall the carburetor mounting screws to secure it in place.

Now, position the air filter cover over the carburetor and secure it with the mounting screws.

Finally, reconnect the spark plug wire to complete the fuel tank reassembly.

Please note that repairing appliances can be hazardous, so ensure you use the proper tools and safety equipment and follow all instructions carefully. If you are unsure about any step, consult a qualified technician.
